I'm sorry if this is a common subject because I really didn't know how to phrase the search it was either going to be too vague or too specific. Preliminary steps taken: Windows Vista. Installed trial version 15. Made sure that Paragon Hot Processing option was included. In settings, made sure hot processing was enabled and Paragon Hot Processing was the method. Selected a drive not destined for backup to be the hot processing drive. Backup Procedure: Used the wizard to create a full backup of all the drives I was interested in backing up. One is the main partition and two are USB drives. Saved as a script and scheduled. Ran scheduled script manually. Tries using VSS. Gets VSS error due to the first partition being FAT32. Any ideas as to why it's trying to use VSS when I specified Paragon Hot Processing? Thanks!
